How difficult is it to configure a router for native multicast?
While the protocols that make multicast work can be extremely complicated, configuring a router is very simple. The following is a very simplified sample configuration for Cisco routers to show what is minimally needed to enable a router for native multicast. In this example, the router is homed only to Sprint and is using Sprint’s RP. ip multicast-routing ip pim rp-address 144.232.187.198 ip pim accept-rp 144.232.187.198 ! int Ethernet0 ip pim sparse-mode ! int Serial0 ip pim sparse-mode Repeat for all interfaces through which multicast traffic should flow.
